SNOW-GUARD AND SLATE-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 618,134, dated January24, 1899. Application filed December 16, 1897. Serial No. 662,229- (Nomodel.)

To all whom it may concern:

Be it known that 1, WILLIAM T. RUSSELL, residing at "Wellesley, in thecounty of Norfolk and State of Massachusetts, have invented Improvementsin Snow-Guards and Slate- Fasteners, of which the following is aspecification.

The invent-ion relates generally to improvements in roots, and moreparticularly to a device adapted for use in securing slates upon roofs.

The object is to combine a wind-guard,snowguard, slate-holder, andantirattler in a single device possessing advantages in point ofsimplicity, durability, inexpensiveness, and general efficiency.

The novelty of the invention lies in the terminal spring-loops of thefastening which serve as an antirattling slate-holder and a snow-guard.

The accompanying drawings illustrate one embodiment of the invention,both separately and applied.

Figure 1 is a View of a roof in course of con struction, showing themanner of using the device; and Fig. 2 is an enlarged view inperspective of the device.

Like numerals indicate corresponding parts.

1 represents the fastening device proper, formed of a single piece ofspring-wire, the same comprising a shank 2, one end, 3, of which ispointed and bent downward for engagement with the framing of the roof.The opposite end is bent upward and then extended parallel with theshank for a distance sufficient to form a spring-loop 4, designed toserve as a slate-retaining hook.

5 represents a loop spring formed by a con tinuation of the hook a andterminating adjacent the latter at a point where the entire force orpressure thereof will be exerted upon the slate confined by the hook.This spring is inclined more or less to render it mosteffective insustaining the weight of the snow and to prevent its sliding.

Referring to Fig. 1, it will be seen that by the use of this fasteningeach slate is held at four points and under thefconstant tension of thespring snow-guards; also, that by reason of the large number of guardsemployed and their even distribution over the roof snow will be heldevenly and banking or sliding rendered improbable, if not impossible.

Having thus described my invention, what I claim is- A combinedsnow-guard and slate-fastener formed of a single piece of wire havingattaching means at one end and bent upon itself, adjacent to theopposite end to provide a slateretaining hook and thence carried aroundinto a loop-spring guard having a free end in advance of the open end ofthe hook, the loop being sufficiently expanded to bring such free end tobear yieldingly against the upper sur face of the slate, for the purposespecified.

In testimony whereof I affix my signature in the presence of twowitnesses.

WILLIAM T. RUSSELL. lVitnesses:
